Inverters Vs Normal Generators

Safety benefits

Some inverter generators come with an integrated sensor that picks up high levels of CO and automatically shuts off the unit when these levels become dangerous in a constricted space.

Some also feature engines that produce less CO emissions.

Power needs

Fuel powered portable generators are a lot more powerful and can reach up to 10 000W, whereas inverter generators cannot generate more than 6000W.

Inverter generators are better suited for camping or RV trips, where you only need to power up some small appliances and charge your electronic devices.

Noise levels

Fuel powered generators generate significantly more noise compared to inverter generators. This is because inverter generators tweak the amount of power used according to demand.

This helps with noise reduction and energy efficiency. Inverter generators are also designed with noise eliminating technology and mufflers to further reduce noise levels.

Portability

Because inverter generators do not generate the same amount of power as fuel operated generators, they come with a smaller engine which makes them smaller and portable.

Price

Due to the more compact design, energy efficiency, stable power, and reduced noise levels, inverter generators are pricier than conventional generators.

This higher price tag, however, is accompanied by a range of advantages that are not found on other types of generators.

Types Of Generators

Recreational generators

Recreational generators weigh anything from 50 to 60 lbs and are engineered to be carried with only one hand.

Most recreational options have a maximum power output of 2000W, and they’re typically a good option for camping or tailgating.

Large generators

Larger inverter generators weigh approximately 250 lbs. They are too large to take to tailgate parties, but can sufficiently power a house. They produce 5000W or higher (at 220V).

These inverter generators can connect to the electrical panel in your home using a safety device called a change over switch. This switch is highly recommended for safety purposes.

Average sized generators

Average sized generators weigh around 80 lbs and sometimes have wheels. They generate anything from 2500W to 4500W but can’t be connected to the electrical panel in your home.

Appliances and other electronics must be plugged into the generator directly, which can pose safety hazards if you do not adhere to certain safety guidelines.

Due to the size of the units, they are generally a good option for recreational vehicles.

They generate enough power for appliances like microwaves or toasters and are lightweight enough to offload and use at a safe distance from the RV.

Features To Consider

Watt level

Before investing in a reliable generator, you should first assess your power consumption needs and overall wattage requirements.

The watt level dictates the amount of wattage you can use to power up your appliances or charge electronic devices simultaneously.

Amount of noise

Inverter generators are typically quiet and generate fewer emissions. They often come with mufflers and noise level reduction technology.

Load sharing

An inverter generator is designed to digitally throttle the engine upwards or downwards according to the demand.

The resulting energy efficiency means you do not need to fill up the gas tank as frequently.

Size

Since inverter generators have smaller engines, they come in a compact and lightweight size.

This makes them a portable and favorable choice for tailgaters, campers, and DIY enthusiasts.
